SoftCMS versions prior to Version 1.6 suffer from the issues.

A successful exploit could allow an attacker to execute arbitrary commands on the target system, as well as gain access to administrative functions of the application.

Moxa is a Taiwan-based company that maintains offices in several countries around the world, including the U.S., UK, India, Germany, France, China, Russia, and Brazil.

The affected product, SoftCMS, is a central management software that manages large scale surveillance systems.

SoftCMS sees action across several sectors including commercial facilities, critical manufacturing, energy, and transportation systems. Moxa said the product sees use primarily in the United States and Europe with a small percentage in Asia.

Moxa SoftCMS Webserver does not properly validate input. An attacker could provide unexpected values and cause the program to crash or excessive consumption of resources could result in a denial-of-service condition.

CVE-2016-9332 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 7.5.

In addition, a specially crafted URL request sent to the SoftCMS ASP Webserver can cause a double free condition on the server allowing an attacker to modify memory locations and possibly cause a denial of service or the execution of arbitrary code.

CVE-2016-8360 is the case number assigned to this vulnerability. Which has a CVSS v3 base score of 8.1.

Also, the SoftCMS Application does not properly sanitize input that may allow a remote attacker access to SoftCMS with administrator’s privilege through specially crafted input.

CVE-2016-9333 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 9.8.

No known public exploits specifically target these vulnerabilities. However, an attacker with a low skill would be able to exploit these vulnerabilities.

Moxa’s suggested mitigation is to update the application (SoftCMS v1.6), which is available for download from Moxa’s web site.
